Wheat is the main cereal crop in Kazakhstan and fertilizers play an important role in enhancing harvest growth. In this study, the impact of new sulfur-containing fertilizers on the growth and yield of wheat was evaluated, and the resistance of varieties to Puccinia triticina Erikss was also investigated. (also known as Puccinia recondite Rob. ex Desm.) for recommendations in agriculture. The study was conducted from 2017 to 2020 in a nursery and greenhouse. The sulfur-containing fertilizer contains nutrients that allow you to extend the duration of absorption by the plant, thereby extending the period of their availability to plants, compared to conventional preparations. By encapsulating molten elemental sulfur and impregnating with a solution of calcium polysulfide, a long-acting compound based on amorphous and monocalcium phosphate was developed. The sulfur is in a water-soluble sulfate form, which, in turn, is slowly oxidized by bacteria and retained in the soil. Three different types of the developed sulfur-containing nano-particle have been used to test in greenhouses and nurseries: powdered, pasty sulfur-containing composition, and a solution of calcium polysulfide. The results showed that the use of powdered and dissolved sulfur-containing fertilizers contributed to the early ripeness and increased productivity of wheat. Wheat varieties were tested for the presence of key Lr genes that determine resistance to brown rust. The Omskaya 29 sample showed an immune response according to phytopathological assessment, and molecular screening revealed four resistance genes. The new sulfur-containing product is recommended for improving wheat productivity in agriculture, and the Omskaya 29 variety can also be used as a valuable breeding material resistant to brown rust.

The biocontrol programs that are currently developed focus on specific microorganisms that live in plant tissues, also known as the endophytes. This article discusses pathogenic micromycete species that infected herbaceous plants growing in the Yereymentau District, Akmola Region. Four fungi species were detected that belong to the same genus. Information about the species composition and a brief description of each fungus were provided. The seasonal behavior of rust fungi was investigated. As it turned out, rust fungi tend to go through the uredinium phase in July and to produce teliospores in September. The research population includes the most common species of rust fungi. This article was first to identify phytopathogenic fungi that attack herbaceous plants in the Yereymentau District and their seasonal behavior. The findings may contribute towards expanding the global fungal database with information about fungal diseases specific to the given region and towards combat against a variety of phytopathogenic fungi.
